IM the person that asked about the 12 disc add on first on my car....i did the research, and luckily found some members that knew more than i did, and we combined our efforts
and there is more than one Wire for the CD Changer....there are 3 wires, and the CD changer and like i said im my previous post, you need the special dock and lock connectors that you cannot purchase anymore from Gm
your best bet is to add an aftermarket changer if you desire
I know theres a harness.. I need to install an ipod adapter, I have something called the aux box... is there a write up on how to add the factory harnesS? I'll just make my own with the wires I have a solder it together.. I don't need the factory sockets.

i can tell you the following
Lt audio signal-Brn/white
Rt audio signal-Dk Grn/White
Audio common-Blk/white
Drain wire
Battery Voltage-Orange
Ground-Black
Class 2 Serial-Data Purple
Class 2 Serial-Data Purple
the all the above wires are contained in a CD changer harness
Thank you,. I actually got it working. I've been looking at wireing diagrams for both my car and the aux box I had and I matched up the wires. So what I did was took off the xm plug which has all the wires I need and hooked it through there. It actually thinks its a cd changer which is cool.. I can scroll through the albums and songs using the steering wheel controls. and the head unit.
In essence, the factory XM and 12 disc changer use identical connections (electrically) into the vehicle (the two connectors are just a different shape). As 1993 SLE mentioned, the trick becomes when the car doesn't have one or the other of the two options. This can require adding wiring into the large connector in the back of the radio bay. Terminals are needed which are near impossible to obtain (although a donor car from an auto wrecker would be an option). If you already have one or the other you can piggyback them together (at the existing device) allowing for your audio input into the HU (which is what GM does). The power, ground and class 2 serial data are straight forward once your audio signal hurdle is overcome
FYI, the CD Changer between an F-Body and what was available for our cars are two different (completely) changers. Whether or not they share a similar harness, that I couldn't tell you. But the changers themselves are different from other GM units not on this platform/vintage.
When I got my Bonneville GXP, I did some extensive checking with the dealer, a Delco/Delphi reseller and a car stereo shop - mine was equipped with the XM, but not the CD changer - they said "cain't be done." Of course, the truly industrious may be able to cobble something together, but the cable, changer, and adapters are none of them available from GM, and the Delphi guy told me that the PART numbers aren't even available - meaning you'd have a challenging time finding the right CD changer that would communicate with the head unit (utilizing the display for track/time/label) if you could fabricate and run the cable.
Everyone says "just get an FM modulator"
Uh, no thanks.
XM keeps me pretty happy, though.
